This works faster than scp and doesn't need any network file systems. 1. On the destination system start netcat listening on an arbitrary port and piping it's output to tar. (Make sure that you're in the right directory, since tar will extract into the current directory. Alternatively you can use the -C option) e.g.: nc -l -p $PORT | tar -xf - 2. On the source system pipe the output of tar to netcat which sends the data over the network to the destination machine. e.g.: tar -cf - $DIRECTORY | nc $HOST $PORT 3. Just sit back and wait :) Cheers Martin -- The IBM 2250 is impressive ... if you compare it with a system selling for a tenth its price. -- D. Cohen
